Heat index

January's mean heat index is computed to be a sweltering 37°C (98.6°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
